Abstract

1494152 Porous thermoplastic resin sheets SUMITOMO CHEMICAL CO Ltd and HAYASHIBARA BIOCHEMICAL LABORATORIES Inc 14 March 1975 [15 March 1974] 10879/75 Heading C3C A porous thermoplastic resin sheet is made by moulding into sheet form a mixture of 100 parts by wt. of a thermoplastic resin and 0À1-50 parts by wt. of a pullulan powder and then immersing the sheet in water to dissolve out and remove the pullulan: the pullulan being a polymer of formula where n=10-10,000. The resin may be polyvinyl chloride, polyethylene, polypropylene, polystyrene or an ethylene/vinyl acetate or acrylic acid copolymer. A plasticizer, e.g. dioctyl phthalate, may be used with the polyvinyl chloride.
